BACKGROUND OF THE INVENTION 10 Magnesium sheets or magnesium alloy sheets are known to have excellent properties such as specific strength and thermal diffusion, but are difficult to plastically process at the time of production and particularly cold (room temperature) plastic working. The magnesium (alloy) plate thus used is preferably used for products such as a body of an electronic device such as a laptop computer, which requires light weight, high rigidity, electromagnetic wave shielding, and heat dissipation. However, magnesium (alloy) sheets are problematic, and it is difficult to form, for example, deep calendering and forming complicated structures such as ribs and convex portions by height, and when forming a complicated structural position, an additional step other than plastic working is required after plastic working, For example, the cutting step and the joining of a plurality of component steps result in high manufacturing cost and reduced productivity. As for the method of improving the plastic working property, the following two methods are used: 20 a method in which thermoplastic processing is performed after the lubricant is applied to at least one of a metal material to be processed or a mold for processing; and a method , wherein the thermoplastic processing is performed by inserting a fluororesin sheet between the metal material and the metal mold. However, when the lubricant is applied and then heated, another problem arises, depending on the temperature, the lubricant may burn and stick to the surface of the mold, 1288032, which makes it difficult to completely remove the lubricant after processing. Further, the fluororesin sheet is problematic, and the fluororesin sheet is hardly formed into a complicated shape because it has a low surface energy and is hardly adhered to a metal material or a mold, and thus is not suitable for a treatment requiring a high processing ability. In both methods, the metal material after processing must be surface protected. Due to the problems associated with the use of the lubricant method and the method of inserting the resin sheet, it has been proposed to improve the processing ability by integrally forming a composite of a resin and a metal, as another solution for achieving a highly processable magnesium material. method. For example, Japanese Patent Publication (JP-A) No. 10 2001-315162 proposes a technique in which a metal plate coated with a thermoplastic resin is subjected to pressure forming, and then formed on the side of the thermoplastic resin layer by molding in a mold. Set ribs or protrusions. JP-A No. 7-124995 proposes a method in which a metal component is coated with a heat-resistant rubber adhesive or a hot-melt adhesive 15 mainly composed of a polyurethane, and the resin is injected and formed in an adhesive state in situ. A rib or a protrusion is formed on the layer at the position. The foregoing technique requires the injection molding of a thermoplastic resin for each of the components, and the improvement of the adhesion of the resin to the metallic material. For example, the former requires two steps, in other words, a plastic working step and a 20-step step in the mold to achieve the desired molding; the latter requires two steps, in other words, the application of the adhesive to the predetermined position and the in-mold forming step, Such problems as complex production processes, poor productivity, and the like are limited by the limitations of injection molding thermoplastic resin materials. When using a resin 1288032 / which is suitable for forming ribs in a mold, etc., it is difficult to maintain a uniform coating under the heating conditions required for plastic working of magnesium (alloy), and therefore cannot be applied to plasticity involving high-temperature heating. Processing. Considering the problem, the object of the present invention is to provide a magnesium (alloy) composite material suitable for thermoplastic 5 (thermoplastic work), which is easy to use thermoplastic molding die 5 without using a lubricant or the like, even if a height is required. Another purpose of the addition of JL processing, such as calendering and forming a complex shape such as ribs and projections, is to provide a plastic magnesium (alloy) product obtained from the composite by a thermoplastic polymer. C SUMMARY OF THE INVENTION 10 SUMMARY OF THE INVENTION Through the results of the research, the inventors have found that the aforementioned problems can be solved by forming a heat resistant resin coating on a ruthenium (alloy) plate, thus completing the present invention. In other words, the composite material of the present invention for thermoplastic processing has a coating layer comprising 15 layers having a melting point or a pyrolysis point 15 (rc or a heat resistant resin coating thereon, deposited on at least a magnesium plate or a town alloy plate - On the side surface, the heat-resistant tree sorghum is preferably a thermosetting resin, and more preferably a thermosetting polyimine resin. From the viewpoint of effect, the thickness of the coating layer is preferably from 1 μm to 250 μm. The plastic processing product of the present invention a plasticized product molded by plastic working at 10 CTC to 350 liters, comprising a composite material useful for thermoplastic processing, comprising a coating layer having a dazzle or pyrolysis point 150 C Or a heat resistant resin formed on the surface of at least one side of the instrument plate or the bismuth alloy plate. The "鎭 or alloy" is occasionally expressed as "town (alloy)". 1288032 has a heat resistant resin coating. The sheet-like composite material of the layer is used as a lubricant when the plastic processing product (molded product) is obtained by thermoplastic processing using a mold heating; the composite material is interposed between the molds by inserting the metal material, and is adjustable from the mold to the metal sheet. The direct stress of the surface; and the softness of the resin coating layer than the 5 metal, the composite material can reduce the friction between the workpiece and the mold. Therefore, the magnesium (alloy) plate can easily obtain a plasticized product having a complicated shape, which is It is difficult to plastically process in the presence of no intervening lubricant or resin sheet. The resin for the resin coating layer of this item needs to have excellent heat resistance. In other words, under the heating condition of plastic working, the shape of the resin layer is required to be 10 It can be maintained without melting or pyrolysis. The characteristic of "no smearing or pyrolysis under plastic processing heating conditions" requires the use of a heat-resistant resin having a melting point or a melting point of 150 ° C or higher, considering the resin coating itself. It may be softened to some extent, but if the resin coating layer flows out in a fluid state during plastic working, or functions due to pyrolysis or carbonization, the effect of the present invention cannot be achieved. As a heat-resistant 15 resin, it is more preferable to use a melting point. Or pyrolysis of a heat resistant resin of 250 ° C or higher. By the presence of a resin coating layer, thermoplastic processing becomes feasible without the use of a lubricant, so there is no need The step of degreasing and washing employs a step of removing the lubricant, which is usually carried out after processing. Such a resin coating layer may be disposed on at least one side, but is preferably disposed on both sides 20, particularly when complex embossing is used. When the mold of the section is subjected to highly processable thermoplastic processing, the effect of the present invention is exerted on the contact surface between the mold and the both sides by providing the resin coating layer on both sides. The advantage of the plastic processed product obtained by the material processing is that after the plastic processing is completed, the resin coating layer remains on the surface of the plastic processed product 288 〇 32, so that no surface treatment is required to prevent vaporization or damage of the surface, usually after plastic working. The surface treatment is briefly described. 'Specific example, the magnesium alloy sheet 1 is a cross-sectional view showing the composite material of the present invention<_ 5 wherein a resin coating layer made of a polyimide resin is formed on the surface on. The dome formed in Example 1 of the present invention is a cross-sectional view showing a plasticized product. t. Embodiment 3 10 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Further details of the present invention will be described hereinafter with reference to the embodiments. Fig. 1 is a cross-sectional view showing a specific example of the composite material of the present invention, in which a resin coating layer 14 made of a polyimide resin having a thickness of 10 μm is formed on both sides of a town alloy plate 12 having a thickness of 0.1 mm. . In order to form a resin-coated 15 layer on a magnesium (alloy) plate, a known method may be used, and a particularly typical method includes a coating method involving applying a resin material to a surface of a magnesium (alloy) plate to form a coating layer; The lamination method involves forming a resin-based film and then laminating the film. The composition of the composite material of the present invention and its manufacturing method will be described as follows. First, '鎭 (alloy) is formed into a plate shape and used as a substrate. The thickness of the sheet is appropriately selected depending on the characteristics of the desired molded product, and the sheet thickness is preferably in the range of 〇〇3 mm to 5 mm from the viewpoint of plastic forming workability. The substrate in the form of a plate is washed and degreased in an ordinary manner to remove the station = and oil from the surface 1288032. Then, in order to improve the adhesion of the substrate to the resin coating layer to be formed, the surface of the substrate may be subjected to a pretreatment such as coating with an adhesion improving agent or a double surface roughening treatment. In this specific example, a substrate in the form of a plate will be described as a case of a material to be subjected to plastic working. However, the material to be processed is not limited to this, and the linear magnesium (alloy) substrate can also be plastically processed to form a coil. When the resin coating layer is formed on the surface of the substrate via a coating method, a heat melting method may be used, which involves applying the hot-soluble gum to the surface of the substrate in an ordinary manner, and then cooling to room temperature to form a resin coating. a layer coating method may be used, which involves drying a resin solution (dispersion) containing a resin dispersed in a solvent or dissolved in a solvent, thereby removing the dissolution j to form a resin coating layer t for applying the liquid resin composition The method can use various technologies. Such techniques include, for example, spray coating, dip coating, rod coater coating, procoat coating, curtain coating, air knife coating, blade coating, and the like. In the present invention, in order to exert its effect, it is preferable to provide a thin and uniform resin coating. In order to achieve the above, the rod coating machine coating, the coating machine coating and the blade coating are used in the above various techniques. Very good. On the contrary, when the resin is applied to the surface of the substrate in the form of a powdery composition, the resin is applied by electrostatic powder coating, followed by baking in an oven to form a coating layer. It is also preferred to prepare the coating by an electrodeposition coating method. When the heat resistant tree layer is formed by a lamination method, the resin film is laminated to the substrate to form a resin coating, and if necessary, the adhesive can be applied to the surface of the substrate. The resin film used for lamination is formed into a thickness of 10 288 〇 32, and the thickness is suitable for use in combination with a resin property by a known method, and is intended to achieve a thickness of the layer. In the step of laminating the obtained resin film on a substrate, the enamel film I is subjected to pressure and heat bonding to improve the adhesion of the resin coating layer. The heating temperature is suitable for the resin characteristics. Usually, the substrate and the resin film to be laminated thereon are heat-bonded and pressure-bonded using a pair of pressure rollers, at least one of which is provided with a heating means. The thickness of the resin coating layer is easily determined depending on the desired molded product, the thickness of the substrate, the shape to be processed, and the type of resin to be used. By forming a thin and uniform resin coating layer, it contributes to plastic processing and prevents the metal sheet from cracking during plastic processing. Further, physical properties such as vibration properties and material texture examples are not deteriorated in the metallic luster and touch of the processed magnesium (alloy). Considering such k points as well as improvement in workability, the thickness of the resin coating layer is preferably from 丄 to 微米. The resin coating layer may be disposed on at least one side of the magnesium (alloy) substrate, but is disposed on both sides of the substrate. Since magnesium (alloy) is easily oxidized, various measures are required during storage before processing to protect the (alloy) surface; but after processing, as shown in the present invention, when a resin coating layer is present on the surface, 汝# 覆层 prevents air (oxygen) from directly contacting the surface to avoid oxidation, so it is necessary to adjust the control atmosphere to obtain another advantage of improved handling properties. 2〇本发”, the resin forming the __ coating layer must maintain the shape of the resin coating layer even under difficult processing conditions, so it must be used; - have a refining point or pyrolysis point of 5GC or above Heat resistant resin, but the surface may soften under these conditions. The heat resistant resin may be a thermoplastic resin or a thermosetting resin as long as the resin has a dazzle 11 1288032 dots or a pyrolysis point of 15 Gt: or more, but it is preferred to use a thermosetting resin. Resin, which is made of a thermosetting resin at room temperature, is easily formed into a uniform film by heating: even if it is heated by the secret addition, its coating properties will change. ', It will be suitable for forming this hair later. 5 脂 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The surface is easily oxidized, so the oxidation position is easily broken during heating processing; or when the surface oxide layer is removed after processing, the strength φ 10 of the region may decrease, so that the metal surface is preferably protected by a resin coating layer, the resin coating layer For plastic processing It is difficult to change under heating conditions, and has sufficient hardness and stretchability. From this point of view, it is preferred to use a polyimide resin which is excellent in self-lubricating properties in the resin coating layer. The polyimide resin also has an advantage in that it is Transparent, it can form a metallic luster on the surface of the town (alloy) board, even if it burns, it will not produce toxic substances such as dioxin. Especially by introducing the ring structure into the resin molecule, it can be made of resin with a pyrolysis point higher than 300 °C. Obtaining a polyimine resin, the polyimine resin is Jialu, and the car father uses a ruthenium copolymer polyimine, which is composed of a tetrabasic acid dianhydride and an aromatic diamine in a lactone compound and a base. In the presence of an acidic catalyst, 20 is obtained by a polycondensation reaction. 'The thermoplastic resin can also be used in the present invention as long as the thermoplastic resin is widely used as a heat-resistant resin for engineering plastics. Specific examples thereof include polyimine resin, poly Phenyl sulfide resin, polyether ketone resin, polyether oxime imide resin, polyamidoximine resin and fluororesin 12 1288032 The resin can be selected according to the purpose of use. The resin of the resin coating layer. The resin may be used alone or in two months! It may be used in a mixture of two or more kinds. In addition, an additive such as a resin which is resistant to the modifier, or may be crosslinked by addition may be used. A modified resin which improves the heat resistance of cross-linked squeaks. ...& The composite material of the present invention thus obtained is subjected to plastic working, + 3 and
